Was diagnosed with RSD about 1 year ago due to a crush injury to the right hand. Eight weeks ago it spread to left arm and hand. Before it spread i had 4 right nerve blocks and today i had my first double block. My question is when it spread i started to get severe headaches. Now i get them at least 5 times a week. My regular Doctor says headaches have nothing to do with rsd. Does anyone else get headaches who has RSD?
